- Quick video explaining the use of gas lifting in order to produce some depleting oil wells. This is very popular in the Permian & Eagleford where Wells could be hit by hydraulic fracturing aka Fracking.
U should upload more these kind of videos on education n spread ur knowledge..so that we get benefitted
This is an in-depth explanation. Many thanks.
I work for Weatherford Gas Lift in the Permian/Delaware, this was a great synopsis of the procedure. i used to work Jet Pumps for Weatherford in the Eagleford a few years ago....keep up the great work.
Appreciate it. Can’t wait till they get rid of all these jet pumps.
I work primarily esp and gas lift but have been interested in jet pump. What's the opposition to it?
I like your simple way of explaining. Thank you.
Creation of a controlled blowout.
Good way of explaining it, I just started pumping like 2 months ago. Its alot more than what I thought, but I love it man. I have a lot of gas lifts on my route.
Good deal; if you have questions feel free to ask. I've been dealing with compression and gas lift for about 5 years now finally starting to feel comfortable with it.
@@JankycattlecompanyI've been out here West Texas in the oilfield for almost 10 years now, touched a bit of every side except pipeline and production. Any tips or leads or where to go or who to talk to about getting my foot in the door as a lease operator?

Im a pge student ...right on this topic....production engineering course...thank you...well explained
I hope you are doing well in your class. There is more than just theory
Thanks for explanation 👍🏼
Great Job
All of the SAGD pads we build are gas lift wells. This is up north on the Devonian.
thank u so much sir
Does those numbers refer to the PTRO set for each GLV ?
Guess you explained the process very well.
Why does the pressure in the casing decrease as the depth of the injected gas increases?
Can you make a video explaining exactly how to read a Barton chart for daily reporting please?
What about without a packer?
So is there a circular gap all the way around the tubing, inside the concrete casing? Or is there another small pipe inside the concrete casing that the gas is pushed through? How does the gas line tie into the casing/well? Great explanation and video of it all though man. I’ve been in the compression industry for 3 years now and still learning new things every day
Are you familiar with downhole set ups? Tubing is 2 3/8” or 2 7/8” that goes inside 5 1/2” or 7 1/2” casing pipe. The space between those two pipes are known as the annulus. This is where gas is injected which will then enter tubing via gas lift valves. The tubing ( 2 3/8”) is isolated from casing with a packer. Hope this helps
can u explain gas lift design and how to make graphs
👍
Great explanation man.
Sorry about the naïve questions but, this type of lift is basically used in lifting the oil from the well to the surface, right? Also the valves on the tubing are mandrel or something else?
Correct to all
Also how about those reducing tubing pressure as we go from surface to the bottom. How that works with mandrel? @@Jankycattlecompany
It’s actually casing pressures that drop. The gas lift valves act as a 1 way check valve only allowed to open at set pressures.
Hi man, What happens if the fluid column in the tubing drops below the last valve(orifice)? will that mean that the well can no longer be produced?
You have to run a blind box tool deployed through slickline to tag your new fluid level. Once confirmed, the next step is to change or rearrange the positions of the GLM in such a way that the live valves will be around the length with the dead fluid and the orifice valve at the bottom.
If there's no further GLM close to new fluid level, the asset onwer may consider running a straddle packer that would create a communication port between the tubing and the annulus. This is a rigless work over operation aimed at redesigning the initial tubing completion design to increase or bring back production.
Packer is kept horizontally like in the drawing?
More so vertical; idea is to isolate the vertical from the horizontal (lateral)
excellent explanation bro..btw what is a dummy valve and how does it work?
A dummy valve basically just fills the slot or hole instead of a live or active gaslift mandrel. They can be wireline or tubing retrievable for future gaslift options as the well depletes.
What do you do when you cant exceed the pressure to open the first 2 valves?
You increase your injection rate by sending more compressed gas into the gas line. Without adequate preset pressure, the valve won't open for unloading
All new wells I've seen in OK have them.
Can anyone explain to me how to use a well rescue pack.
Well if the rescue well pack you are using is the same as the one I use. Well what I do. Is I shut in the well for 15 to 30 min. If I get over 80 lbs of build up. At that time. Then I drop the rescue pack sticks. Leave it overnight. Then the next day I open it, or flare it. If I don't get a build up pressure over 80lbs in 30 minutes. I shut it in overnight. Or until I get maximum build up pressure. Then drop the sticks, and then wait until the next day to open it.
I have a question. If you were to measure the carbon footprint of this system, what part do you think affects it most? And what would you choose as sensibilities to see how can you have less emissions?
BWAHAHAHA!!! Idiot.
Can you explain the calculate formation gas in gas lift well?? Please
Total gas minus the induced gas equals the formation gas.
Yadi yada yada
How many types of gas lifts do we have ?
Couple. Conventional (inject through casing flow through tubing, multiple valves) and annular (inject through tubing flow through casing, multiple valves), I’ve got a new style that uses higher pressure (2500psi) to inject down the casing and only uses 1 gas lift valve.
something i'm not paid enough to know🤣
Don't be so casual ...be more informative
What wasn’t informative? I’m not an engineer, I just operate these systems.
@@Jankycattlecompany yes it is! But ur casualness breaks our attentions.. this topic needs a greater in-depth knowledge.btw u did fare work.🌹
Finish your thoughts in the form of a sentence. You know your stuff but you can't teach it!!!
